I suspect solar (including wind/biomass) + batteries is going to trounce fission reactors in the not terribly long term. If you think of finance in terms of latency/bandwidth (a model I use for lots of things), reactors are high latency - they're expensive and take a long time to set up.
Meanwhile, solar/wind is heading toward dirt cheap and trivial to set up. Environmental impact is minimal, too. It doesn't require giant corporations, government sponsorship, complex regulations, or exotic engineering skills to implement. With those incredible advantages, it doesn't need to be cheaper than nuclear - it just needs to be adequately cheap.
